Hi, I've been reading a lot about NTFS and Time Machine, but I'm still wondering whether I could backup to an external USB drive (not networked). According to this post, it's possible to achieve this on a network drive: (Images extracted from the original post) But as far as I understand, you need the .sparsebundle file, which is not created when backing up to an USB attached drive. At least, I'm not seeing the file on my system.log, as that post states. Any ideas? Thank you PS. I'm using Tuxera to be able to write to NTFS drives.
